i had some of my rock against the glass and i had very little circulation behind them. also like melissa said, i had a snail get stuck on his back behind them and i needed to remove most of the rock from the area jsut to help him up. i personally think the island in the middle of the tank looks the best because it gives more viewing room, not only in the front but also behind it. and the circulation ,which is key in a sw tank depending on what you are keeping, is soo much better .
